A close low-angle study of a Douglas A-1 Skyraider on the ground, looking aft along the port side. At left, the cowling of the Wright R-3350 radial engine, its cooling gills open and its exhaust outlets trailing heavy soot streaks along the fuselage. The cockpit canopy is slid fully open with a helmeted crewmember inside, and above it the outer wing panel stands folded vertically, showing the carrier-derived wing fold retained when these Navy airframes passed to the Air Force. The camouflage is visibly sun-faded, chipped and stained by hard use. In the foreground at right, a maintenance stencil on a rack or store reads 'RELEASE STUD BY PULLING' and refers to a release cable. No tail code or serial appears in this crop. Project: 219827
